Hello team im trying to find out how to match up my psu so i can upgrade it. right now i have this exact 1 on this link http://store.ramplus.com/atatred2hpp5.html I dont understand or cant find what connecters im gonna need to come with it? Also i just upgraded my integrated chip with a 7600 GS (256)AGP 8x, this card calls for at least 350 watts and 18-20 amps on the 12volt rail. Now for the catch; i was told on an hp chat my pc could go to 350 watts and should be no problem, Now they also told me there was an upgraded psu for 400 watts, which was confirmed by a supervisor. How ever i need to extend my warranty for them to tell me specs other then 400 watts, i need to know about the amps on that 12 volt rail etc, to make sure im actually getting what i need. This will be my last HP as i run it to the ground for their qualifications for support. hehe. Anyway i do have this new card now so i didnt know if i can get soemthing more specific for it (extra agp connector for agp card)? I have searched for days but like i said these connecters i have now im not sure of because the only place i can find the specs are at that link. I appreciate your time and help? I have an a735w hp pavillion (holiday bundle package) on a pantherlite chasis if more info needed please let me know? Im aware of my dimensions and see i can only increase in the depth(from back of motherboard increasing psu to the front of mb).

Hi grassi,

Your model hp has a Asus board in it therefore you can use any stardard atx psu so I would forget about dealing with HP or there supplies.

http://www.techsupportforum.com/f70/outdated-power-supply-information-and-selection-107466.html

If you read over that and pick a recommend psu you should be ok

Please note: You will have to watch dimensions of the psu you pick and make sure it fits your case the last time I changed one in a HP there was not alot of room, you may have already mentioned that but just making sure

help please

hello im back with a question, lol, as you can see im having a hard time, and been through 2 psu's but i keep getting the wrong ones. I was told i need at least 18-20 amps on a 12 volt rail. Can someone tell me what this link states for specs as it shows 2 12 volt rails, and now im confused. I need that 18 not 16, should i find one with just 1 18-20 amps on a 12 volt rail? what did i get myself into, just when you think you have all the info, they get me...oh and since i have a new AGP card should i be looking for or is there any options on a psu where i can have an extra 4 pin power connector to come straight from psu to my video card? Right now i have to jump in with my cd/dvd or my samsung hardrive(i think thats what it is)?

make sure your existing unit is NOT a micro ATX

measure the height, width and length of the psu frame of your existing unit and post them in here. dont worry about super exact measurements to the nearest 1/4 inch will be fine! :wink:

wow thanks guys for your help, But i didnt explain myself enough sorry. I have this one
http://www.power-on.com/atx12v250bt.html
i contacted hp to do this the easy way but i needed to join their warranty program to get specs and tech support to buy their upgraded psu. I did get to find out that this cpu has only been tested with a 400 watt tested psu. So i dont want to try anything over 400? Okay i have done some searchin and found these in the order i like them.

http://www.tigerdirect.com/applicat...30&Sku=ULT31839&SRCCODE=NEXTAG&CMP=EMC-NEXTAG
this one has 8 peripherals, so i can actually come straight out of psu to my new video card, instead of jumping off my dvd/cd power or my samsung hard drive. which i do now.

http://www.affordablesurplus.com/compaq-254475-001-power-supply.asp

im just not sure as far as connectors go if these or atleast my favorite choice has the same connectors as my current psu? Please tell me if my 1st current psu link matches my 1st option for a new psu. (the black one)? As far as dimensions, i can figure that one out thank god.

Your current HP PSU that you linked (best whatever) is a wired to the standard powersupply wiring. I just verified that!

The HP unit you have and linked has the wiring pin out if you hold your mouse over the 20 pin connector / when compared to the standard wiring pattern shown here
http://pinouts.ru/Power/atxpower_pinout.shtml (they match)



this is the unit I would get; if I were in your shoes

or if you are budget restricted

okay, your 1st link was over 400 thats pushin it, i dont want to try anything that hasnt been tested and 400 is the only wattage tested so your 2nd link
http://www.newegg.com/Product/Product.asp?Item=N82E16817104953

seems to be better but im still not understanding, the reviews here say it had some "cons" as my other one had good reviews, how did you know about failure rates? Also this psu seems to have pci connector i have agp? dont understand that? I do like the 6 peripherals. Im also wanting at least 18-20 amps on the 12 volt rail, so my v-card makers say. so this has 2 +12 volt whats that mean? Will it use the one that says 18amps for my card?

Most of the newer PSU's will all work in your system as long as you have enough room in there to fit it. There is no maximum barrier for a PSU that you can break :grin: Its generally very well to obtain one which is more than sufficient for your system specs -- remember upgrades :wink:

The OEM supplies are not a valid choice for you and nether is the Ultra unit which was on for free for 4 months because its so bad. You'll most likely end up losing your system along with a PSU with such products.

Bear in mind your PSU should be of the utmost quality, reliability and known good efficiency. It is the single product that runs everything on your system, so its the most crucial and demanded. It needs to be the "best" possible to run anything under it with stability.

The above Antec 550W and Forton 450W are very good choices for anyone withs such requirements. Antec 650W was on a deal for $60 after rebate which just expired yesterday :sad:

The Antec TP3 550W is on here for $93.15 if that takes your liking: http://www.mwave.com/mwave/viewspec.hmx?scriteria=BA23050

The fortron 400 will suit your needs just fine


the PCI express video card power connector is of no use for you & your current system. as you have stated you need AGP.

if your AGP card needs and additional power plug it will be molex.

a power supply only puts out the power they system needs and no more, the easier the PSU's work load the longer it lasts and the better it will run. There are no electrical devices I have seen yet that like to be loaded anywhere near max capacity.

if you want cheaper , look here

in actuality this unit probally suits you the best ****** price & quality of Sparkle is VERY good

okay maybe do you have a little more options for me, With better reviews. I tried searchin those 2 but dont think there that great. From reviews. Does antec make the better quality psu? If you can give me some more options with more detailed specs, i would appreciate it. i would rather have 350-450.
But that 12 volt rail is important to me. Oh i know im a little late but New Egg...im not happy with, I can copy paste your findings to see if there else where. thanks

you can read reviews and customer feedback until your eyes cross.

Things you must realize, there are far more people that have abused the lower wattage units because they are cheaper to buy.

Example: a computer enthusiast builds a specification that should have included a high quality 550 watt unit, but instead he opts to buy a well known name brand unit (fortron) in 450 watts becasue its 50.00 instead of 100 dollars for the 550 watt unit. When the unit fails who do you think he blames ?????? yeah, not himself for cheating the spec requirement.

You will also need to learn the "game" of interpretaion of PSU reviews. Seldom do they come out and say, unit XYZ is junk dont buy it!

instead they will use crafty wording and avoid heaping praise on a unit, does that translate to it being a good unit ? not hardly

now when you read a tech review regarding a high quality "real" work horse unit, you should immediatley see the difference. They will; & rightfully so, baste the unit in praise.

so in summary; it takes a degree of experience and open mindedness to evaluate what they are really saying, without letting our own personal cravings effect our interpretation.
I am often bewildered at how I can read the same review as another poster, and he immediately clinges to any "positive" comments in the review due in large part to the eagerness of cheaper price.


On the Antec topic:

Antec has good units; antec has mediocre uints. The Trio~~~ TP3 series is a very good line of units; they have a 430 watt version which would work very well for your box, its not an under $60.00 dollar unit ! but its far better quality and horse power than any we have discussed above.
http://www.newegg.com/Product/Product.asp?Item=N82E16817103942


google searches for reviews on any unit will get you a taste and feel of consumer experience, as well as tech opinions.


BTW: tigerdirect.com zipzoomfly.com


goodluck

okay im going back to your link here...
http://www.newegg.com/Product/Product.asp?Item=N82E16817104954
I guess really this one is okay. I dont want to go cheap, but 100 dolars for this is too much thats 1/4 of what i paid for this whole set up. Antec i heard was good but cant find any on tigers direct that would be good? Can i have one from Antec preferably from tigers of your choice, high amps on that 12 volt rail please. The above will be my choice if i have no other luck here. thank you, im learning a lot really. JJust takes some questions, had we been talking in person it wouldnt be so difficult. Thanks again.

That has a total of 36 amps on the +12v, so it will be able to run pretty much any card that a 450 w PSU would have enough power for. I think that is a good choice linderman gave you.
